Enrich a previous GMLAS database not working

[sgrellet]

Environment

• Plugin version: 1.4.0-beta4:
• QGIS version: 3.16.16-Hannover, f5778a89
• Operating System: Windows 10 1909
• Python version: 3.9.5 (tags/v3.9.5:0a7dcbd, May 3 2021, 17:27:52) [MSC v.1928 64 bit (AMD64)]

Description

• running the following test scenario "https://brgm.github.io/gml_application_schema_toolbox/testing/scenario_mode_gmlas_local.html#"
• instead of trying to create a new SpatialLite DB, append, update, overwrite a previous one leads to nothing happening

To Reproduce

Steps to reproduce the behavior:
Attached file :
20220127_20210625_BoreholeViewB_test_update.zip

1. follow the "Relational mode (GMLAS) scenario - Local test scenario" (cf link above)
2. when comes the point of connecting to a SpatialLite DB, point to the one attached
3. choose either append, update, overwrite
4. no layer is loaded, no python error just the following message in the plugin log

"2022-02-04T11:00:40 NONE Setting impex_import_method saved with value 1
2022-02-04T11:00:41 INFO Temporary configuration file created 'C:\Users\grellets\AppData\Local\Temp\gmlasconf_qxf_s1rv.xml' for conversion.
2022-02-04T11:00:41 NONE Opening GMLAS file 'https://raw.githubusercontent.com/BRGM/gml_application_schema_toolbox/master/tests/basic_test_scenario/0_BoreholeView.xml', using the configuration file: 'C:\Users\grellets\AppData\Local\Temp\gmlasconf_qxf_s1rv.xml'
2022-02-04T11:01:00 NONE Let's load it!"

Expected behavior

• the database should be properly loaded (tables, links (pk, fk) and also the geometry) with the content that correspond to the outside XML content and also to the action 'append', 'update', overwrite'
